The Super Seal™ Junior has a standard sealing head that seals cap diameters up to 83 mm. It is a high powered hand held induction cap sealer that is ideal for laboratory applications, contract packaging, short run production and start-up operations. Its compact design makes this an ideal portable cap sealer. A digital timer, batch counter, foil counter and missing foil indicator makes this induction sealer very easy to use with repeatable results. Prevent leaks, preserve freshness and extend shelf life just like the high speed packagers with Super Seal Junior.
